Sleeve pack

摘要

A sleeve pack to be used with a pallet base and cover to form a container for shipping bulk goods comprises four vertical walls arranged such that each vertical wall is orthogonal to two adjacent walls. At least one vertical wall of corrugated plastic is joined by an edge-to-edge butt welded seam. In a preferred embodiment of the present invention a vertical wall panel having vertically oriented corrugations is edge-to-edge butt welded with a corner piece of corrugated plastic having horizontally oriented corrugations to form a continuous one ply sleeve pack. An alternative embodiment of the present invention is a double thickness, corrugated plastic sleeve pack in which one thickness has horizontal corrugations for side impact resistance and the other thickness has vertically oriented corrugations for increased stacking strength but with all seams butt welded.
